Abstract

The invention relates to a testing apparatus for straw cutting performance. The testing apparatus is composed of a mechanical system and a measurement and control system, wherein the mechanical systems comprises a rack, a cutting device and a conveyer device; the measurement system comprises a force sensor, a speed sensor, a data acquisition card, a programmable automation controller (PAC) and a personal computer (PC). The testing apparatus for the straw cutting performance and the method are simple and compact in structure, can perform continuous cutting and data acquisition on different portions of one or more straws in one test, increase efficiency of a cutting test and save time. The testing apparatus can perform related tests for different cutting conditions such as cutting ways, cutting tools, cutting speed, cutting angles and the like, thereby allowing the functions of a testing bench to be more comprehensive and providing experimental data and evidence for the research and development of cutting machines.

Description

Technical field [0001] The invention relates to a straw cutting performance test device and a test method thereof, belonging to the technical field of measuring devices, and is used for testing the straw cutting performance. Background technique [0002] As the stalk of crops, straw is a multi-purpose renewable biological resource. More than half of the photosynthesis products of crops exist in straw. At present, the use of straw is mainly concentrated in four areas: livestock and poultry feed, industrial raw materials, returning to the field as substrate or fertilizer, and converting into energy. The first step of these utilization methods is to cut and crush the straw. There are many kinds of straw, and the cutting and crushing performance is very different. At the same time, because the value of the straw itself is not very high, therefore, from an economic point of view, the straw should not be over-processed, and the processing energy cost should be as low as possible. Par...
